HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 712,338, dated October28, 1902.

Ap'lliimion flied Mmh 7, 1902. serial No. 97,075. (No model.)

To all whom, it Wawy concern,.-

Be it-known that I, TILDEN SHANK, a citizen of the United States,residing at Glass, State of Alabama,have invented anew and usefulImprovement in Hay-Presses, of which the following is a specilication.

My invention consists of an improvement in hay-presses of a suitablebody portion with a plunger moving therein and guides for said plungerand means for operating the same.

Figure l represents a plan view of a haypress embodying my invention.Fig. 2 represents a partial side elevation and a partial sectional viewon line a; x, Fig. 1. Fig. 3 represents a partial sectional view on liney y, Fig. l. Fig. 4 represents a sectional view on line a a', Fig.- 2.

.Similar letters of reference indicate corresponding parts inthefigures. l

Referring to the drawings, A designates a hay-press having a box orframe which is of unusual construction and has the usual central openingtherethrough in which is mounted and'guided aplunger-head D, to Which ispivotally attached a plunger-arm E, which latter is bifurcatcd at oneend and has mounted therein a wheel F, which is journaled on a pin G,the ends of which project and on which are mountedv the rollers U.Pivoted at H to a suitable portion of the frame is a crank-arm J, whichis provided with bifurcated ends K and L, whichare adapted to engagewith the rollers U on the pin G when said crank-arm is properly'turned,the latter having a crank M thereon Vfor manipulation thereof. p

N designates a cam or quadrant which has the slot P therein in which theWheel F is adapted to travel and is guided thereby.

Q designates a spring whichis suitably attached to the plunger-arm E andto the frame of the machine, said spring being adapted to return theparts to their Anormal position after operation.

R designates a bar which is mounted on the frame of the machineand whichis suitably guided in slots in the' ears S, secured to the frame B, aspring T being adapted to return the said bar to its normal positionafter it has been moved therefrom.

In the sides of the frame B are the slots or openings C, in which arethe elbow-arms V, which have the shoulders W, which project ,intotheinterior of the frame B, said arms being connected with suitable springsA, which are adapted to hold the same normally in position, as shown inFig. 4.

The operation is as follows: The hay or other material is placed Withinthe casing and the crank M operated to turn the crank-arm Juntiloneend-foreXample,L-contacts with the rollers U on the pin G, whenthe said crank-arm is movedin the direction indicated by the arrow. Theplunger-arm E is forced in the direction indicated by the arrow, beingguided by reason of the roller F moving in the slot P, which is in thequadrant N. This operates the plunger-head D to press the hay, andthespring Q returns lthe plunger head and arm to their normal position,when the crank M is operated in the opposite direction, it being seenthat when the hay is being pressed by the plunger D it will force outthesprings V through the opening C; but after the pressure on the arm Vceases the springs A will force in the arms V ,to the positionseen inFig. 4, and the shoulder W will prevent the hay from springing back.

It willb evidentthat various changes may be made by those skilled in theart which will come within the scope of my invention, and

I do not, therefore, desire to be limited in every instance to the/exactconstruction as herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isv 1 In a press,abody portion,a plunger-head,a plunger pivotally connected therewith and bifurcated at its outer end,a roller carried in said bifurcated end, a fixed quadrant embraced bysaid bifurcation and having a camslot in which said roller travels and abifurcated crank-arm embracing the plunger and engaging meansindependent of said roller carried by the latter to actuate the same.

2. In a press, the combination of a-body portion, a plunger-head movabletherein, a plunger pivotally connected with said head and bifurcated atits free end, a roller mounted in said bifurcation, rollers uponopposite sides of the same; a quadrant with a cam-slot and IOO acrank-arm having bifurcated ends to enito brace the plunger and quadrantand to enbrace the plunger and quadrant and to engage said. outerrollers. gage said outer rollers, and means for return- 3. In apress,the combination of abody poring; the plunger and head to their normalpotion, a plunger-head movable therein, a plunsition.
